Title: Production of high purity silica sol
Inventor: WATABE YOSHITSUGU
IPC: C01B33/141
Filed: 1990-01-20
Abstract: PURPOSE:To improve film-forming property of silica sol produced by reacting silicofluoric acid or ammonium salt thereof with NH3 in an aqueous medium, separating the deposited silica from the aqueous medium, washing with water and then subjecting to wet pulverization in a specific silica concentration. CONSTITUTION:An aqueous solution of silicofluoric acid of 5-40wt.% as H2SiF6 is brought into contact with NH3 gas or 5-28% aqueous solution of ammonia at 0-100 deg.C so that SiO2 concentration in the reaction mixture becomes 0.5-12.5% and further, as necessary, an inorganic salt such as NH4F is added thereto at a ratio of 0.5-5mol based on 1mol H2SiF6 to deposit silica. Then the deposited silica is separated and recovered from the reaction mixture by filtration, etc., and washed with water to provide a deposited silica having low impurity content. The deposited silica is dispersed into water and subjected to wet pulverization in water under 2-50% SiO2 concentration to provide nearly neutral aqueous sol or to provide an organosol when pulverized in an organic solvent.

Title: Power supply control system
Inventor: TANIMARU SENKICHI
IPC: H02J1/00
Filed: 1985-01-24
Abstract: PURPOSE:To guarantee the operation of an information processor after a power supply is turned on or off and to lighten the load on an operator by adding an inhibiting condition interface to an information processing system. CONSTITUTION:At the output of a power supply ON indication signal to the information processor 12, a power supply control device 1 decides the status of a power supply ON signal outputted from the inhibiting condition interface 400, and when the signal is not in the inhibited status, outputs the power supply ON indication signal. The processor 12 is turned to the power supply ON state and returns a power supply ON completion signal. Simultaneously, the processor 12 establishes an I/O interface 120 between the processor 12 and a device 21 and continues to send a power supply ON inhibiting indication signal to an information processor 13 through an inter-control device interface 100 until I/O operation is validated. Then, the device 1 tries to output a power supply ON indication signal to the processor 13, but stores the skipping of the processor 13 without outputting the power supply ON indication signal because the power supply ON inhibiting signal is sent from an inhibiting condition interface 401 to the processor 13 to shift the control to the succeeding information processor. Thereafter, the skipped information processor is retried several times.

Title: Formation of soi substrate
Inventor: HASHIMOTO MAKOTO
IPC: H01L21/306
Filed: 1996-01-26
Abstract: PROBLEM TO BE SOLVED: To realize uniformity in thickness of an SOI layer within a wafer plane while ensuring throughput. SOLUTION: A surface 11a of a silicon substrate 11 formed in an irregular shape is covered with an insulator which is to be an abrasion stopper layer 12, and an abrasion substrate 16 is bonded. By chemical abrasion using a liquid abrasive made of an alkaline solution, the silicon substrate 11 is abraded from the back side to a state such that a protruding portion of the silicon substrate 11 is left. In this case, when a part of the abrasion stopper layer 12 is exposed, the density of the liquid abrasive is reduced by approximately 1/100. Thus, the etching rate of etching of the protruding portion of the silicon substrate 11 left between protruding surfaces 12a of the abrasion stopper layer 12 using the liquid abrasive is lowered, and the thickness accuracy of an SOI layer 10 made of this protruding portion is secured.
